Prerequisite (s): General Biology II (0304102)

Level: 2 nd and 3 rd year

Lectures time: 09:00-10:00, Sun., Tue., and Thu.

Course description:

This course covers the fundamentals and applications of microbiology, providing students with a basis for understanding the broad aspects of the biology of microorganisms. It provides students with basic knowledge regarding microbial structure, physiology, growth and nutrition, genetics, and taxonomy. Environmental, industrial, medical and food microbiology will be covered. This course includes the fundamental training in the field of microbiology to enhance students practical capabilities in the field of microbiology. The practical part serves many functions; it helps student to practice standard microbiological staining and culture techniques as well as microbial purification, identification, and verification techniques.

Learning outcomes

After completion of the course, the students are expected to:

 Identify microorganisms on the basis of structural, morphological, and biochemical examinations.

 Get familiar with microbial evolution and systematics (microbial taxonomy)

 Understand the difference and the relation of microbes to other species.

 Get familiar with the growth and metabolism of microbes.

 Understand how microbes respond to changing environments in order to survive.

 Understand how to control microorganisms by physical, chemical, and antimicrobial agents.

 Get familiar with microbial ecology.

 Know about microbial genetics (i.e. essentials of molecular biology, mutation, genome structure, cloning, and gene function and regulation).

 Understand how the immune system constantly protects us from infection.

 Know about microbial diseases and epidemiology.

 Know what separates “good” or commensal microbes from “bad” or pathogenic microbes

 Get familiar with microbial biotechnology, industry, and genetic engineering.
